FLAME-SPREADER FOR OIL-LAMP BURNERS.

Specification of Letters Patent.

Patented Sept. 26, 1916.

Application filed May 6, 1916. Serial No. 95,757.

To all whom it may concern Be it known that 1, CHARLES E. GoDLnY, a citizen of the United States, and residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and Improved Flame-Spreader for Oil- Lamp Burners, of which the following is a specification.

This invention relates to burners for oil lamps and particularly to the flamespreaders thereof, and its object is to provide a flame-spreader that will insure perfeet combustion of the oil, and therefore, a perfect flame which is symmetrical in form andwithout soot or smoke.

This invention consists of a novel circular flame-spreader crowned upwardly having holes at both sides and at both edges of the wick tube, and so fitting within the cone of the burner that the air entering through perforations in the cone above the edge of the flame-spreader will be deflected upwardly.

1n the accompanying drawing, Figure 1 is a partial elevation and partial section of an oil lamp. Fig. 2 is a vertical section of a cone and an elevation of the remainder of a burner. Fig. 3 is a plan of a flamespreader. Fig. 4 is a plan of the cone. Fig. 5 is an elevation. of adjoining parts of a body and an oil-font of an oil lamp.

Similar reference characters refer to like parts throughout the several views.

In the accompanying drawing, the lamp shown is of a well known down-draft type having a body 1, a font 2, a lens 3, a lens door 1, and a lining 5. The top 6 of the font is provided with a flange 7 having slots 8 into which extend the pins 9 on the flange 10. A second ring 13 is turned in at 12 around the inner edge of the top 6 of the font and has a sealing flange 14; that engages a sealing flange 15 on the top.

The burner consists of the usual base 16, basket 17 deck 18, wick-tube l9 and rachet stem 20. The cone 22 has a skirting formed of the radial flange 23 provided with holes 2%, and the cylindrical portion The cone is provided with a circumferential row of holes 26 that are positioned just above the outer edge of the flame-spreader 27, which is secured to the upper end of the wick tube.

The flame-spreader is made of thin sheet metal, brass preferred, and is substantially frusto-conical, that is, it slopes up from the' spreader which is, one inch in diameter to be quite satisfactory.

r The cone of the burner is held in position on the basket and the burner on the font by means of the resilient fingers 29 on the ring 30 secured to the lining 5.

The flame-spreader is formed with two larger holes 81 opposite each other atthe sides of the wick-tube and two smaller holes 32 between the larger holes, which holes permit the upward flow of air which enters through the holes 33, passes down between the lining 5 and body 1, passes through the holes 24 and around beneath the cylindrical. portion 25 of the skirting into the cone and thence upwardly through the holes 31 and 32 to the flame. Some of the air will pass up around the cone through the ring 30 and enter the holes 26 and pass to the flame.

The exact reason for the superior action of this flame-spreader is not clear, but the probability is that the crowning of the flame-spreader so as to bring its middle portion up to the top of the wick-tube, and its upward slope from below the holes 26, has a most beneficent effect. The top of the wick-tube is preferably slightly below the lower ends 35 of the flame opening 36.

' I claim:

1. In an oil burner, the combination of a wick-tube, a flame-spreader at the upper end of the wick-tube having a circular edge and sloping upwardly to the wick-tube, said flame-spreader being provided with four holes, one at each side and one at each edge of the wick-tube, and a cone fitting the flame-spreader and having a circumferential row of holes just above the edge of the fiame-spreaden 2. In an oil burner, the combination of a wick-tube, a flame-spreader at the upper end of the wick-tube having a circular edge and sloping upwardly to the wick-tube, said flamespreader being provided with four holes, one at each side and one at each edge of t e Wick-tube, and n fitting t flame-spreader and having a eircmnferenupper end of the Wick-tube and sloping tial row of holes just above the edge of the downwardly from the upper end of said flame-spreader, the lower ends of the flame tube to a circular edge and having holes at 10 opening in the cone being just above the th sides and edges of the Wick-tube, and

5 upper end of the Wick-tube. a cone surrounding the Wick-tube and 3. In an oil burner, the combination of a flame-spreader. Wick-tube, a flame-spreader secured to the CHARLES E. GODLEY.
